Core Advantages

"Golden Size" 600mm Reach — Covers 90% of Standard SCARA Workflows

The 600 mm arm reach is the most universally applicable arm length for industrial SCARA applications. It spans standard conveyor-to-conveyor transfer distances, fits dual-row tray layouts, and covers most pallet layer patterns without requiring mechanical repositioning of the robot. If you are deploying a SCARA for the first time and are unsure which arm length to choose, the S600-B-4 is the correct starting point for 90% of use cases.

±0.03 mm Repeatability — Consistent Precision Across Full 600mm Workspace

Despite the longer arm compared to the S450, the S600-B-4 maintains the same ±0.03 mm full-workspace repeatability as the rest of the S Series — delivered through absolute-value servo drives on all four axes. For picking flexible soft-pack pouches or small pharmaceutical containers where misalignment causes product damage, this level of positional consistency matters throughout an entire 16-hour shift.

Absolute Value Servo — Instant Restart After Any Power Event

Absolute encoders retain axis positions through power cuts, e-stop events, and controlled shutdowns. In a three-unit parallel deployment (such as the Thailand case study below), all three robots resume from exact position on power restore — eliminating the multi-minute re-homing and inspection cycle that incremental-encoder robots require. Over a year of multi-shift operation, this saves dozens of hours of production downtime.

Built-In 6×2 Pneumatic Interface — Ready for Gripper in Minutes

Six dual-channel pneumatic tracheal ports are routed through the arm body at the factory. Pneumatic parallel grippers, vacuum cups, and multi-nozzle suction tools connect directly — no external tube routing, no additional fittings, no custom bracket fabrication. In environments involving chemical or food packaging, keeping the exterior arm profile clean and sealed reduces contamination risk.

220V AC 50/60Hz Universal Power — Global Drop-In Deployment

The S600-B-4 operates directly from 220V AC at either 50 Hz or 60 Hz — the industrial standard across most of Asia, Europe, the Middle East, Africa, and Latin America. No step-up transformer, no frequency converter, no facility electrical modification required. For factories deploying across multiple countries or exporting production lines, this eliminates a common hidden cost.

Application Scenarios

S Series Model Selection Guide

S Series Comparison Table

Selection guide:

• Choose S450-B-4 if: workstation width is below 500 mm, parts are small, the robot must be moved frequently between stations, or cycle time target is ≤ 0.85 seconds.

• Choose S600-B-4 if: you have a standard pick-and-place or sorting application, conveyor width is 500–700 mm, or you want the model with the broadest compatibility — the S600 is the recommended default.

• Choose S800-B-4 if: parts exceed 5 kg, the workspace spans more than 700 mm, or the application involves larger pallet footprints.

SCARA vs 6-Axis Robot — Which Is Right for Your Application?

Rule of thumb: For the vast majority of sorting, pick-and-place, and flat-layer assembly tasks, a SCARA costs less to buy, runs faster, breaks down less, and is easier to reprogram than an equivalent 6-axis robot. Choose 6-axis when the task genuinely requires rotating a workpiece to arbitrary angles in 3D space — welding, deburring, complex surface finishing.

Customer Case Study

By Fannie Chen, CEO, Shenzhen Guanhong Automation Co., Ltd. (SZGH) | May 2026

A factory owner in Thailand reached out to us about a sorting problem that, on the surface, seemed straightforward: 500g liquid hand-soap pouches, sorted and packed into export cartons, at roughly 18,000 pouches per eight-hour shift. Three conveyor lines running simultaneously.

The complication was the product itself. Liquid chemical pouches — even mild household cleaners — create an environment where prolonged human handling is uncomfortable and, over time, a health concern. His workers were developing skin irritation from the residual chemical vapour. He had tried cycle rotation and gloves, but turnover on the sorting floor was climbing. He needed to remove people from the process entirely.

The S600-B-4 was the right tool. I recommended three units, one per conveyor line, running in parallel. The 600 mm reach matched his conveyor width exactly — no mechanical adjustment needed. The built-in 6×2 pneumatic interface let us connect chemical-resistant gripper tooling directly to each arm.

The precision question was the one he kept returning to. Soft pouches are deformable — if the gripper closes even slightly off-centre, the pouch gets pinched and may leak. With ±0.03 mm repeatability, the S600-B-4 hits the same pick point on every cycle. In more than six months of operation, he has reported zero pouch-breach incidents attributable to robot misalignment.

Three robots replaced nine sorting workers on those three lines. But the number he cited when we spoke afterward was not the headcount reduction — it was the 40% lower estimated maintenance cost compared to the 6-axis alternative he had also been considering. I had walked him through the lifetime cost calculation: fewer servo axes, simpler kinematics, lower spare parts frequency, faster technician training. The SCARA economics were not even close.

The line runs sealed now. His workers are on other tasks. And the pouches arrive at the boxing station intact, every time.

Frequently Asked Questions

Why is 600mm the most recommended reach length for a SCARA robot?

The 600 mm arm reach spans a typical dual-lane conveyor layout (300 mm per lane), fits most standard pallet layer patterns, and covers the working radius of the majority of 3C electronics, food, and chemical sorting workstations. It is the "golden size" because it avoids the two most common sizing errors: choosing a reach too short (robot cannot cover the full work zone) or too long (robot overshoots, increasing cycle time unnecessarily). When uncertain, choose 600 mm.

What is a SCARA robot and when should I choose it over a 6-axis robot?

SCARA (Selective Compliance Assembly Robot Arm) uses horizontal rotary joints for fast XY-plane motion plus a vertical Z-axis — 4 axes total. Choose SCARA when your task is fundamentally a horizontal pick-and-place, sorting, or flat-layer assembly. It will be faster, cheaper, and easier to maintain than a 6-axis robot for these tasks. Choose 6-axis when you need to rotate a workpiece to arbitrary 3D orientations — welding, complex surface finishing, or multi-angle insertion.

Can the S600-B-4 handle flexible or soft packaging (pouches, sachets)?

Yes, with appropriate end-of-arm tooling. The S600-B-4's ±0.03 mm repeatability ensures the gripper contacts the pouch at the same point every cycle, preventing off-centre clamping that causes leaks or tears. Pair it with a wide-jaw pneumatic gripper (connected via the built-in 6×2 tracheal interface) or a vacuum suction array for soft-pack applications. See the Thailand case study above for a documented 18,000-pouch-per-shift application.

How many units can run in parallel on one production line?

There is no system-level limit on the number of S600-B-4 units operating in parallel. In the Thailand chemical sorting case, three units ran simultaneously on adjacent conveyor lines, each with its own controller. Synchronisation between units (e.g., shared conveyor tracking) is handled via digital I/O or Ethernet communication between controllers. SZGH's engineering team can advise on multi-robot line layouts.

Does the S600-B-4 need re-homing after a power interruption?

No. All four axes use absolute-value servo encoders that retain position data through power loss. When power is restored — whether after a planned shutdown, emergency stop, or unexpected outage — the robot resumes from its exact last-known position with no homing sequence required. In multi-shift, multi-unit deployments, this eliminates a significant source of accumulated downtime.

What is the total cost of ownership difference between SCARA and 6-axis robots?

For equivalent pick-and-place workloads, a SCARA robot typically has approximately 40% lower maintenance costs over its service lifetime compared to a 6-axis alternative. The reasons are structural: fewer servo axes (4 vs 6), simpler kinematic calculations reducing controller wear, lower spare parts frequency, and shorter technician training time. The initial purchase price is also lower. For high-volume sorting or assembly applications running two or more shifts per day, the lifetime cost difference is substantial.

Is the S600-B-4 suitable for chemical or corrosive environments?

The standard S600-B-4 is designed for general industrial environments (5°C–45°C ambient). For applications involving chemical vapour, corrosive splashes, or high humidity (such as liquid cleaning product sorting), SZGH recommends discussing IP54-rated enclosure options and chemical-resistant surface treatment variants. The built-in pneumatic interface can be fitted with chemical-resistant tubing and fittings. Contact export02@szghtech.com for environment-specific configurations.

How does the S600-B-4 compare to the S450-B-4 and S800-B-4?

All three models share the same ±0.03 mm repeatability, absolute servo drive system, Z-axis stroke (+100/−80 mm), and speed specs (Axis 2: 720°/sec, Z: 800 mm/sec). The key differences are arm reach (450 / 600 / 800 mm), robot weight (15 / 20 / 25 kg), and maximum payload (5 / 5 / 8 kg for S800). Choose S450 for the tightest spaces and maximum portability; S600 as the standard versatile option; S800 for heavier parts or wider conveyors.
